Fatigue tests

DYNA-MESS testing machines can be used for fatigue tests for many kinds of of materials and components. As an example, the fatigue tests are used to determine the SN curve of a material.


Cost-efficient servo-pneumatic

DauerschwingversuchFor many applications DYNA-MESS fatigue testing machines are equipped with a servo-pneumatic actuator by reducing significantly the cost compared to a servo-hydraulic testing machine.


Fatigue behavior

To determine its fatigue behavior, the specimen is exposed to a force and displacement controlled load - if necessary, a static pre-load can be applied on the specimen. The load applied on the specimen can be tension, compression or a combination of those two types of loads. The experiments can be performed with different waveforms or as a multi-stage (block) experiment.

  • Sine
  • Triangle
  • Rectangle
  • ...

Dynamics properties

With DYNA-MESS testing software it is possible to measure different dynamic characteristics of a material as:

  • Dynamic stiffness
  • Loss angle
  • Strength loss
  • ...

The corresponding properties are calculated and presented on a graph. Thus, it is possible to have a statement about the change of the specimen's properties during the test.

Tolerances can be defined by the user in order to stop the test if the testing parameters are not respected due to an abnormal behavior of the test part.

Continuous data recording

By continuously recording data throughout the test period, it is possible to have a statement not only about the type of damages or change in the test parameters but also the evolution of the damages or parameters while performing a test. All data is automatically recorded for further documentation.
